Trichocereus thelegonoides ‘JLcoll.4378’ (syn. Echinopsis thelegonoides) | Seeds

Hardly ever available on the collector’s market, Trichocereus thelegonoides (syn. Echinopsis rubinghiana, Echinopsis thelegonoides and Trichocereus rubinghianus) is an extremely rare cactus species which is native to regions of Argentina. We’re lucky enough to have acquired a small quantity of fresh thelegonoides seed, collected by renowned cactus authority Joël Lodé. Considered to be endangered in the wild, this is yet another of our UK exclusives!

Taking a sprawling, shrub-like form, thelegonoides puts out upright yet ground-hugging stems which can reach six metres in length. These stems comprise fifteen or sixteen, slightly-notched ribs and can be quite thick toward their base, with the thinnest parts generally being five to eight centimetres in diameter. The plant’s yellow-to-brown, thorny spines reach roughly half a centimetre to four centimetres long, turning greyish as the plant matures. As with most of its fellow Trichocereus species, Trichocereus thelegonoides flowers only at night, forming fragrant, white-whitish, funnel-shaped blooms grow to fifty centimetres or more. The flowers are followed by ellipsoid to spherical-shaped fruits of roughly five centimetres in diameter.

The species’ name is a reference to it’s similar appearance to Trichocereus thelegona, hence the name thelegonoides – ‘resembling thelegona‘. Usually to be found growing on dry inclines at altitudes of between five thousand and two thousand metres, it occurs naturally in USDA Hardiness Zones 10-11, but can be grown in Zones 8 and 9 as well. Easy and rewarding to cultivate from seed using standard techniques, Trichocereus thelegonoides is drought-tolerant and has average water requirements. Sow in mildly acidic to mildly neutral soil in anything from full sun to light shade. Space young plants at least two metres apart to allow them enough space to reach their full potential.

This really is a rare opportunity to grow an even rarer cactus which every Trichocereus fanatic should have in their garden!
